Sublime Text 3 and High DPI on Linux

30 Aug 2014

A previous
post regarding Sublime Text 3 and High
DPI screens on a Linux system was nothing more than a bad workaround, if that.
Fed up with a bad looking situation, I decided to delve deeper into things.
Mentions were there of changing the value of text-scaling-factor using
gconf-editor, gsettings or dconf-editor, but doing so made absolutely no
difference for my Sublime. In the end, I stumbled upon a simple Sublime
setting.

Indeed, a setting, so you can just go ahead and open your user preferences
(Preferences → Settings - User). Next, add the following line: "dpi_scale":
2.0. If you have not yet changed settings here before, the file has to follow
the JSON format, so be sure to place the appropriate
commas. After adding the line, save the file.

With the setting changed and saved, just restart Sublime Text. Everything
should finally be readable again, without a need for nasty workarounds.
